Overview Glutamine is the largest store of amino acid in the body, with large amounts being stored in the muscle. Glutamine accounts for over 60% of the total intra-muscular amino acid pool. However, release rates are so high that even in resting muscle it is likely that all these stores would be used up within 7 hours if de-novo synthesis did not take place. During exercise release rates from muscle increase dramatically, leaving both muscle and plasma levels depleted for between hours and days depending on the duration and intensity of the exercise. Glutamine levels have been shown to be low in athletes with over training syndrome, and much recent research has focused on its role in the prevention of this syndrome. What is it? SNI’s Glutamine Peptide is derived from partially hydrolyzed ( pre-digested) wheat gluten. It contains a concentrated amount of peptide-bonded glutamine. Each 5 gram serving (1 teaspoon) provides 1.5 grams of glutamine peptide. It also is high in pure protein. (80%) Why is it better that pure L-Glutamine? The advantage that Glutamine Peptide has over pure L-glutamine is that the gastrointestinal tract prefers peptides to whole proteins or amino acids; hydrolyzed proteins are more easily broken down and absorbed into the blood stream than whole protein sources [Ziemlanski et al. 1978]. In fact hydrolyzed proteins may be absorbed in about half the time that it takes free form amino acids or whole proteins. This can lead to a more rapid delivery into the body, especially when it is needed most (like after weight training workouts). Also much of the pure L-glutamine (free-form amino acid) gets absorbed or consumed by the natural flora found in the digestive tract which leads to improved immunity, but it is not providing fuel or the building blocks for improved muscle mass. A major advantage is less is needed to achieve the results body builders desire. ( ie better recovery, increased muscle mass.) References:
